Remove the unnecessary inclusion of disklabel.h in cd9660_vfsops.c so
that I don't have to worry about the latter when changing disklabel.h.

Supply prototypes for some functions that were implicitly declared and
fix the resulting warnings and errors (timevals were punned to timespecs).

8db02de884 Added MCOUNT_ENTER and MCOUNT_EXIT macros to profile.h
Removed inb function since it's more correctly in pio.h

Copied write_eflags and read_eflags over from npx.c

(Some changes to the macros suggested by Bruce were not made at this
time since his suggestions probably apply to all the macros and
these inlined/macro definitions need a lot of cleaning up at some
point in the future.)

Fix from Bruce Evans. There were missing sets of parantheses:

1. The checks for the standard data selectors were botched, so %ss == 0
   and probably %cs == 0 were allowed.  A fix is enclosed.  The checks
   for the standard selectors could be omitted without losing anything
   since the standard selectors pass the valid_ldt_sel() tests.

f86233fe54 Added a bit of missing functionality to make this work correctly on a

pci_config.c (I hope this is what was intended; my system works ok).
Use pmap_mapdev().  Automatically map any large linear frame buffers
or whatnot in VGA-style devices which ordinarily would not have their
own drivers, and don't call not_supported() for them.  (This shuts up
complaints about my Matrox card.)  Include the beginnings of what could
eventually become dynamically-loadable PCI devices.  Allow for the
possibility of PCI devices simply providing a PCI veneer over an existing
ISA device, and shut up about them, too.
Make autoconfiguration text conform more to the style of other supported

Poul-Henning Kamp
5b7ffe398f Digicom Systems Inc, makes "softmodems". What this means is simply that
you download the microcode to the DSP everytime you power on your system.
They provide a dos-program to do so, but no other support.  This commit adds
code to the sio-driver, which implement an ioctl, which will down-load the
micro-code.

To get this functionality, you must define DSI_SOFT_MODEM.

The program to actually employ the ioctl is not included, but the entire
source looks like this:

        #include <sys/ioctl.h>
        #include <stdio.h>

        main()
        {
                unsigned char buffer[100000];
                int i;

                read(0,buffer,100000);
                if((i = ioctl(1,TIOCDSIMICROCODE,buffer)) < 0)
                    perror("ioctl");
                return i;
        }

And you use it like this:
	smload < data144b.dsi > /dev/ttyid3

You need to copy the *.DSI files from the dos-media provide with your modem.
You can see what is downloaded by issuing the ATI3 command to the modem.
DSI's scheme for what code you can run on your modem isn't violated by this.

30902edcfb ProAudioSpectrum 16 {Zilog|Ncr} 5380 based SCSI-driver.
This puppy is in good shape now.

It is a fully blown SCSI-driver, but it isn't a high performance one.  It is
implemented entirely with polled I/O, and is intended to drive CD-ROM's, not
disks and tapes.  It will run disks and tapes if asked to, but it isn't a
very good idea to do so.  Transfer-rates max out at 600-700 kbyte/sec.

There is one problem: when write-requests get over 8192 bytes, the pseudo-DMA
stalls.  This is only a problem if you dd(1) to a raw-device of some kind,
for mounting a disk it is ok.  I have circumvented this by disabling the
pseudo-DMA in those cases.

It's very unlikely that I will spend more time on improving the performance
of this driver, it can do what I want it to now: install from a CD-ROM, and I
don't see any benefit in actually adding interrupts to the driver, considering
that performance never will be better than 700 kbyte/sec anyway.

You can install it under 1.1.5 too, by adding the lines to files.i386, your
config-file and copying pas.c and ic/ncr_5380.h over.

I will fix any bugs I can get a handle on.

Garrett Wollman
f0068c4a70 Initial get-the-easy-case-working upgrade of the multicast code
to something more recent than the ancient 1.2 release contained in
4.4.  This code has the following advantages as compared to
previous versions (culled from the README file for the SunOS release):

- True multicast delivery
- Configurable rate-limiting of forwarded multicast traffic on each
  physical interface or tunnel, using a token-bucket limiter.
- Simplistic classification of packets for prioritized dropping.
- Administrative scoping of multicast address ranges.
- Faster detection of hosts leaving groups.
- Support for multicast traceroute (code not yet available).
- Support for RSVP, the Resource Reservation Protocol.

What still needs to be done:

- The multicast forwarder needs testing.
- The multicast routing daemon needs to be ported.
- Network interface drivers need to have the `#ifdef MULTICAST' goop ripped
  out of them.
- The IGMP code should probably be bogon-tested.

Some notes about the porting process:

In some cases, the Berkeley people decided to incorporate functionality from
later releases of the multicast code, but then had to do things differently.
As a result, if you look at Deering's patches, and then look at
our code, it is not always obvious whether the patch even applies.  Let
the reader beware.

I ran ip_mroute.c through several passes of `unifdef' to get rid of
useless grot, and to permanently enable the RSVP support, which we will
include as standard.

c784172318 Detect if we're running on a Cyrix 486DLC and enable automatic cache
negation whenever we access memory between 640k and 1M.

Original code from NetBSD 1.0-BETA.  The exact origins are unclear but
Theo de Raadt, Charles, and Michael V. may have contributed to it.

12365022c0 Make it possible to run lptcontrol on a printer port which does not
actually have a printer connected or online:
- MAKEDEV:		remove all signs of lpa
			add lpctl? devices (minor # = unit + 128)
- usr.sbin/Makefile	add lptcontrol
- sys/i386/isa/lpt.c	implement the LP_BYPASS flag: when a unit is
			opened with this flag set, the printer is
			not primed, and no check is made to see that
			the printer is online.  This can only be used
			to pass ioctls.  (giving us /dev/lpctl?)
- lptcontrol.c		use /dev/lpctl? (LP_BYPASS)
			-f flag removed, -u flag added
- lptcontrol.8		document changes in lptcontrol
			rewrite using mandoc macros

c4ff2eb1dd Newly implemented ioctls list:

CDIOCEJECT.

CDIOCPLAYBLOCKS removed (old implementation completely wrong and I don't
know how to implement it correctly).

All routines now detects media change correctly.

DELAY_GETREPLAY increased for long time access from first track
to last.

mcd_waitrdy() now use MIN_DELAY=15 as minimal delay which independs
of machine speed.

mcd_doread() now uses real status (old code uses obsoleted soft copy of it).

clear XBSY on error in mcd_doread()

mcd_statrt(): add missing splx(s), cause dead hang with unmatched slpbio()

optimize mcd_doread(), don't set CD mode each time, keep soft copy of mode.

call getdisklabel() _after_ mcdsize() for proper sizes

mcdopen(): old code forget to set MCDREADRAW in flags when open RAW
partition, doread check it for setting RAW CD mode.

Do nothing on stray interrupt (which sometimes occurse, because driver
read data block too slow, DOS driver use 'insb' here). Old stray code
cause timeouts.

Read toc entries code rewritten to return many requested entries
(as supposed) instead of one entry with incorrect structure.

CMDREAD2 requests covered with disable_intr()/enable_intr()
(from DOS driver)

Read junk code added after read block code in doread (from DOS driver)

mcd_read_toc() code fixed to read all needed entries, old code cause
some audio tracks is not played.

mcd_playtracks() code fixed to proper check valid track range.

New binary read modes implemented (from DOS driver).

generate lists of assembler source files so the lists to be mkdep'ed
have to be given explictly.  Only the standard *.s files are given,
so the dependencies for gnu/fpemul/*.s are incomplete.  *.S files
would be handled right if config put them in CFILES.

Don't define NPX.  It was replaced by NNPX > 0 years ago.

Define LOAD_ADDRESS in COPTS so that compiling machdep.c isn't a special

3e0a35fee4 Updated to final 1.1.5 version (revision 1.56).
Merged changes from 2.0 version (revisions 1.46-1.50) by hand.

Finished conversion to clists: removed flush of tty output buffer
in comflush() (most writes were truncated to 256 bytes) and restored
bypass of ttyinput() in siopoll().

Finished conversion to 2.0 types - more void *'s, less caddr_t's,
less casts, no Dev_t's.

Only these things are seriously broken now compared with 1.1.5:
waiting for output complete is impossible so ttywait() can deadlock;
sioclose() isn't called enough so sioopen() sometimes returns EBUSY
unnecessarily; input flow control is not implemented.

f0b544e99e Restore the intr_* array variables that were removed in the previous
revision.  They caused redundant redeclaration warnings because I
forgot to declare them as extern and gcc-2.6.0 treats "extern int x[];"
slightly different from "int x[];" (this is probably a bug).  The new
versions will cause RR warnings from gcc-2.4.5 because it does not
understand that the second declaration in "extern int x[]; int x[1];"
is not redundant.  The variables don't actually need to be declared
in a header file because they are used in only one C source file and
one assembler source file, but I want all public variables and
comments about them to be findable by grepping *.h.

This is the slowest and most stupid of our SCSI-drivers, but it is there

It uses no interrupts, no DMA, just polled I/0.
Transfer-rate is <= 100Kbyte/sec.
If you set the jumpers on the board, you can change the unit-number and
you will be able to have four of these co-exist in one computer, why one
would do that is somewhat unclear though.
If I ever get my hand on the docs for this, I will improve it of course,

	o Fake int 8 for rtc as well as int 0 for clk.  Required for kernel

/usr/src/sys/i386/isa/isa.c:
	o Allow isdp->id_irq and other things in *isdp to be changed by
	  probes.  Changing interrupts later requires direct calls to
	  register_intr() and unregister_intr() and more care.
	  ALLOW_CONFLICT_* is brought over from 1.1.5, except
	  ALLOW_CONFLICT_IRQ is not supported.  IRQ conflict checking is
	  delayed until after probing so that drivers can change the IRQ
	  to a free one; real conflicts require more cooperation between
	  drivers to handle.
	o Too many details to list.
	o This file requires splitting and a lot more work.

/usr/src/sys/i386/isa/isa_device.h:
	o Declare more things more completely.

/usr/src/sys/i386/isa/sio.c:
	o Prepare to register interrupt handlers as fast.

/usr/src/sys/i386/isa/vector.s:
	o Generate entry code for 16 fast interrupt handlers and 16 normal
	  interrupt handlers.  Changed some constants to variables:
	  # $unit is now intr_unit[intr].  Type is int.  Someday it should
	    be a cookie suitable for the handler (e.g., a struct com_s for
	    sio).
	  # $handler is now intr_handler[intr].
	  # intrcnt_actv[id_num] is now *intr_countp[intr].  The indirection
	    is required to get a contiguous range of counters for vmstat
	    and so that the drivers depend more in the driver than on the
	    interrupt number (drivers could take turns using an interrupt
	    and the counts would remain correct).  There is a separate
	    counter for each device and for each stray interrupt.  In
	    1.1.5, stray interrupt 7 clobbers the count for device 7 or
	    something worse if there is no device 7 :-(.
	  # mask is now intr_mask[intr] (was already indirect).
	 o Entry points are now _XintrI and _XfastintrI (I = intr = 0-15),
	   not _VdevU (U = unit).
	 o Removed BUILD_VECTORS stuff.  There's a trace of it left for
	   the string table for vmstat but config now generates the
	   string in one piece because nothing more is required.
	 o Removed old handling of stray interrupts and older comments
	   about it.

Added my if_lp TCP/IP driver to lpt.c.
I have (surprise) not been able to test it on a 2.0 machine yet.  Connect the
machines with a parallel "lap-link" cable, and get rates from 35 kbyte/sec
up to 75 kbyte/sec.  (when ftp'ing foo: dev/zero -> bar:/dev/null).

The same lpt.c file should compile under 1.1.5.1 without problems.

I think we should promote this feature when we dump 2.0 on the expectant
public, because it provides a cheap and efficient way to move data to and
from notebooks &c.  It is not a replacement for ethernet, but a cheap

to come later.)

4c5483f462 Initialize lockf pointer. I missed this when I made NFS use the generic
advlock mechanism, and not doing so results in random system crashes.

9ae159169a Make it easier for programs to figure out what revision of FreeBSD they
are running under.  Here's how to bootstrap (order is important):

1) Re-compile gcc (just the driver is all you need).
2) Re-compile libc.
3) Re-compile your kernel.  Reboot.
4) cd /usr/src/include; make install

You can now detect the compilation environment with the following code:

#if !defined(__FreeBSD__)
#define __FreeBSD_version 199401
#elif __FreeBSD__ == 1
#define __FreeBSD_version 199405
#else
#include <osreldate.h>
#endif

You can determine the run-time environment by calling the new C library
function getosreldate(), or by examining the MIB variable kern.osreldate.

For the time being, the release date is defined as 199409, which we have
already established as our target.

2e0cc1821d Some programs (like GNU configure programs) depend on the output of
`uname -s' to be something reasonable (traditionally, `i386') rather
than `PC-Class'.  Make it so.

28b5c68f2f Fixed vm_page_deactivate to deal with getting called with a page that's
not on any queue. This is an old patchkit days fix.

4b43e1d8ca Removed some padding bytes from the nfsnode struct to make the structure
size a power of 2 again. The system complains otherwise - probably because
it wastes space with our malloc scheme otherwise.

52cd438439 Merge in the necessary bits from 1.1.5.1 to make exec.h and reloc.h
happy campers again (e.g. match our own exec format).  This should
make ld happy.
